“…However, it should be kept in mind that aural polyps may be related to serious pathologies other than COM as seen in our case. Xenellis et al (10) reported that, among the patients they operated on with an initial diagnosis of COM and with a polypoid mass in the external ear canal, cholesteatoma was the main pathology in the majority of the cases (86.7%). However, other lesions like glomus tumor, melanoma, mucosal adenoma, fibrous dysplasia, squamous cell carcinoma, adenoma of the endolymphatic sac, encephalocele, and tuberculosis were reported in the remaining patients.…”

Myxoma is a benign connective tissue tumor that arises mostly from the heart. Temporal bone myxomas are extremely rare and these patients should be evaluated for the Carney complex association. Herein, our aim was to present a middle ear myxoma case operated with an initial diagnosis of chronic otitis media (COM) and to underline the fact that myxomas should be kept in mind in the differential diagnosis of aural polyps.

“…Furthermore, in cases of masses that totally obstruct the canal, only radiological investigations may reveal the exact extent of the mass. The clinical finding of a “polypoid mass” in the EAC in cases of otitis media in up to 13% of cases may present with atypical diagnoses that differ from the traditionally expected diagnosis of middle ear cholesteatoma [13]. …”

Tumors originating from ceruminous glands are rare lesions of the external auditory canal. The lack of specific clinical and radiological signs makes their diagnosis challenging. We report the case of an exceptionally rare benign tumor, a syringocystadenoma papilliferum (SCAP), in an atypical location in the bony segment of the external auditory canal with uncommon clinical signs. The special traits of the case included the following: the most lateral component of the tumor was macroscopically cystic and a granular myringitis with an obstructing keratin mass plug was observed behind the mass. The clinical, audiological, radiological, and histological characteristics of the neoplasm are consequently presented. Intraoperative diagnosis of the epidermal cyst was proposed. The final diagnosis of SCAP was determined only by histological analysis after the surgical excision. The educational aspects of the case are critically discussed.

“…CT results were somewhat harder to evaluate because of the high bone resolution and lower resolution mucosal layer. Given that our MRI and CT data were not exactly comparable, and previous reviews have commented on the inaccuracy of imaging OM [7], histology served as the point of reference. From histology results, we are able to confirm the utility of MRI for imaging MT as an inflammatory marker of OM.…”

Objective. Otitis media (OM) is characterized by increased middle ear effusion and inflammation of middle ear tissue. In this study, we compared two radiographic methods of analyzing inflammation by measuring mucosal thickness (MT). Methods. 28 chinchillas were divided into three treatment groups consisting of a vehicle control group and two glucocorticoid groups. 6 underwent treatment by vehicle control, 10 were treated with ciprofloxacin 0.3%/dexamethasone 0.1% (DEX), and 10 received ciprofloxacin 0.2%/hydrocortisone 1% (HC). 96 hrs post-LPS inoculation, chinchillas were euthanized and their temporal bones were removed for analyses. Results. MRI scans (F = 146.0861, P-value <0.0001) and histology (χ 2 = 40.5267, P-value <0.0001) revealed statistically significant differences in MT measurements among treatment groups, whereas CT imaging did not. DEX-treated chinchillas exhibited overall significantly smaller MT values. Conclusion. Imaging MT was effective for determining severity of inflammation due to OM. Previous gold standard methods using histopathology compromise tissue integrity by chemical manipulation and dehydration effects. MRI and CT scanning are viable tools to preserve tissue and examine changes in MT. In this study, MRI provided more information about internal, soft tissue structures. In a clinical setting, MRI could be used for diagnosing and tracking severe or chronic OM.
